ipu7-drivers

This repository supports MIPI cameras through the IPU7 on Intel Lunar Lake platform. There are 4 repositories that provide the complete setup:

• https://github.com/intel/ipu7-drivers - kernel drivers for the IPU and sensors
• https://github.com/intel/ipu7-camera-bins - IPU firmware and proprietary image processing libraries
• https://github.com/intel/ipu7-camera-hal - HAL for processing of images in userspace
• https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api (branch:icamerasrc_slim_api) - Gstreamer src plugin

Content of this repository

• IPU7 kernel driver
• Kernel patches needed

Dependencies

• Kernel config IPU_BRIDGE should be enabled when kernel version >= v6.6.
• Kernel config INTEL_SKL_INT3472 should be enabled if camera sensor driver is using discrete power control logic, like ov13b10.c.
• The camera sensor drivers you are using should be enabled in kernel config.
• For other camera sensor drivers and related ipu-bridge changes, please go to IPU6 release repository.

Build instructions:

Three ways are available:

1. Build with kernel source code tree (in-tree build)
2. Build with kernel headers only (out-of-tree build)
3. Build and install by dkms (DKMS build)

1. In-tree build

• Tested with kernel v6.8 and v6.10

1. Check out kernel source code
2. Patch kernel source code, using patches under patch/<kernel-version> and patch/<kernel-version>/in-tree-build depending on what you need.
3. Copy drivers and include folders to kernel source code.
4. Enable the following settings in .config:

   CONFIG_VIDEO_INTEL_IPU7=m
   CONFIG_IPU_BRIDGE=m
   

   And other components, depending on what you need:

   CONFIG_PINCTRL_INTEL_PLATFORM=m
   CONFIG_INTEL_SKL_INT3472=m
   CONFIG_VIDEO_OV13B10=m
   CONFIG_VIDEO_OV02C10=m
   CONFIG_VIDEO_OV05C10=m
   

5. Build you kernel

2. Out-of-tree build

• Requires kernel headers installed on build machine
• Requires dependencies enabled in kernel, and patches under patch/<kernel-version> (not in-tree-build) applied to the kernel you will run the modules on
• To build and install:

   make -j`nproc` && sudo make modules_install && sudo depmod -a

3. Build with dkms

• Register, build and auto install:

   sudo dkms add .
   sudo dkms autoinstall ipu7-drivers/0.0.0
